    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Sort by new please! Don't look just at the hot category. Also the community is very small! There is no fun if there are only few people active! Let's spread the network and make the community bigger!

We should make a few tutorials on how to get started. It can be very intimidating - I seldom understand the code posted by others.

#improved performance

u/pavel

Original runs at 6fps on my machines this runs at 60fps. I lowered the resolution by a quarter (4x perf) and golfed 13 chars to let me declare all vars locally (2x perf).
u/tomxor

wow! this is a massive perf improvement, the original was impressive but I couldn't really see it realtime. Nice one :)

Most of them are just one big comment or one long string though

eWuW='.,gttb/PIdd ]I]8fte6?Abnu80<~pI~u' It's still quite impressive that it can find any... I guess reducing the length to 40 substantially increased the probability. The next logical progression would seem to be to let it accumulate shorter evaluable strings and compose a larger one from them.
u/tomxor

If you can also fit in the requirement to reduce entropy then you have the seeds of life inside a dweet :D
u/katkip

yeah
u/katkip

u/tomxor

I tried that but couldn't fit it, so I did the opposite - reduce the search space - I made one that constructs expressions for f(t) and does the canvas bit for it so it actually draws: d/12492
